Description

The Fields object represents a collection of columns in a table. The term field is synonymous with column. Each table in a database has an ordered collection of fields, there is always at least one field in a table. The ordered collection behaves like a list, so it is possible to access individual fields by a numbered position (or index) in the list.

CoClasses that implement IFields

Remarks

The IFields interface provides information about a Fields collection and also provides access to individual fields. When using IFields::FindField, remember that there are equivalent methods on IClass and ICursor�they are shortcuts which save you having to get the Fields collection.

When programming with ArcMap, there is a distinction between IFields and two other interfaces, ILayerFields and ITableFields. ILayerFields is particular to an ArcMap layer, so for example, an alias name belongs to the field as defined in that layer rather than being stored with the underlying table.
